Ok what about:
Shannon stands in a beautiful art gallery full of curious objects (scissors, pen knives etc) when the whole place shakes like an earthquake.
She sees people building a roller coaster from piano pieces, asks to come along (ground is still shaking).
They ride up the throat, into the mouth, quickly chuck a shiny bit of metal, close up on humans face, surprised.
Big party in the art gallery, the ground stopped shaking, a cheerful melody is being played on a piano, everyone is happy.
I think that would fit into a minute, but I feel like I'm missing something important! Any help is greatly appreciated :)
